To allwhom it may concern: y

Be it known that we, JonN Bnaxowoon, THOMAS BnANnwooo, and EDWARD BRAND- wooo, all subjects of the King of Great Britain and Ireland, and all residents of Bury, in the county of Lancaster, England, have invented certain new and useful Improvements in the Gaseous or like' Treatment of Textile Materials, of which the following is a specification. v

This invention relates to improvements in that process of fixing dyes or the like which are wound upon perforated cores by forcing air externallyand radially through such yarns. The-perforated cores carrying the dyed yarns are contained in a vessel to which air is admitted under pressure, the air passing through the wound yarns and the perforated cores. ess into effect in the ordinary manner the amount of air supplied is .of such small quantity and is under such low pressure, as for example, when supplied from a blower, that it cannot pass into and penetrate the substance of the yarns especially when they are tightly wound, but escapes through. the spaces or interstices between windings or layers of windings. The component yarns, therefore, are only superficially treated, and as the interstices in some parts of a cop or the like will provide easier passage for air than those in some'other parts, an unequal fixing eflect is obtained even upon superfices of the yarns. This and the fact that the interiors of the yarnsare" not tregted equally with their surfaces results in stripes and spots in the fabrics produced from the yarns. v I

According to this invention the air is supplied in such large volume and at such high pressures that it cannot all pass through the interstices between yarns, an a'la-rge quantity of it is actually caused to ass through the interiors of even the most tightly wound yarns. With this treatment there is thorough oxidation of the dye contained in the innermost parts of the substance of ,all yarns, and a regular color eifect is thus obtained.

In carrying this invention into effect any convenient pressure above atmospheric may be used and for some uses pressures up to a hundred pounds per square inch may be employed.

In carrying such a procbear the cops The accompanying appliances by means of which our invention may be carried into effect.
